also for the netherlands person, i searched up the goonsicoexposed and mynameissicotruth tiktok account, and you should be aware that it is possible to find the region of the two accounts (they are based in NL), sicos simps are doxxers so they will try to break in and get your information or at least find more info such as phone number or email, even if you are doing the good thing by shining some light on her actions, you should be aware of the potential risks 
her close friend group are insane so at least try to protect yourself by making a throwaway accounts not connected to any of your real ones or by using a good VPN.
